It's so close to the edge, at least in this resolution, I think it brings my attention all the way to the very right edge, but there isn't much there. I just feel like it throws off the composition.

And it's probably intentional, and looks kind of cool, but I guess it's a bit weird that it's "behind" the orange clouds at the bottom/foreground? It looks like it is anyway, if you look at the top right edge of that orange part. I usually think of nebulae as background elements, at least when it's huge swaths like that, so it's throwing me off.

Hope I wasn't too judgmental, it's still very good, I really like the colors.

Great planet, very interesting patterns. And the nebula looks like we're up really close to its edge too yet even being relatively near it we are still several star lengths away, as implied by the fact there are small stars still between us and it
